For nearly two hundred years, Caesalpinia echinata wood has been the
standard for modern bows. However, the threat of extinction and the enforcement of trade
bans have required bow makers to seek alternative woods. The hypothesis tested was that
woods with physical, mechanical and acoustic properties similar to those of C. echinata
would have high potential as alternative woods for bows. Accordingly, were investigated
Handroanthus spp., Mezilaurus itauba, Hymenaea spp., Dipteryx spp., Diplotropis spp. and
Astronium lecointei. Handroanthus and Diplotropis have the greatest number of similarities
with C. echinata, but only Handroanthus spp. showed significant results in actual bow
manufacture, suggesting the importance of such key properties as specific gravity, speed
of sound propagation and modulus of elasticity. In practice, Handroanthus and Dipteryx
produced bows of quality similar to that of C. echinata.
